mdolman, I too purchased an arranger as a songwriting tool. I do not play keyboards other than holding down chords and sometimes making synth noises.I was looking for a drum machine that played intros,fills, and endings, and also played in 3/4 time. Well they don't exist! Then one day I found this website with all these interesting people discussing "Arrangers". Would these things do the job? Yes indeed! And more than drum tracks, I get bass parts, keyboard parts, even horn parts. I add various guitars and vocals and get a very workable demo. I learned so much on this website,which is great because I sure didn't get any help at the local music stores. Thanks to all who make this place such a class act.
